Embodiment Construction

[0029] The present invention aims to determine the position of the perforator vessels in the perforator flap preoperatively by a non-invasive method before making any incisions.

[0030] figure 1 The device for non-invasive application by ICG fluorescence imaging (determined by tissue perfused skin during surgery, especially before surgery) is schematically shown. An infrared light source (eg one or more diode lasers or LEDs with peak emission at about 780-800 nm for exciting fluorescence in the ICG) is placed within the housing 1 . The fluorescent signal is detected by a CCD camera 2 with sufficient near-infrared sensitivity; such cameras are commercially available from several vendors (Hitachi, Hamamatsu, etc.). The CCD camera 2 can have a viewfinder 8 , but the image can also be viewed during surgery on an external monitor, which can be part of the electronic image processing and evaluation system 11 .

Abstract

A method and an apparatus for preoperative identification of a perforator vessel for plastic and / or reconstructive surgery using ICG fluorescence angiography imaging are disclosed. Time-resolved image processing is used to highlight perforator locations and to enable visual discrimination among candidate perforators by various computed metrics. Based on these metrics, the surgeon is able to interactively locate and select perforator vessels suitable for plastic and reconstructive surgery.

Description

Background technique [0001] Plastic and reconstructive surgery often requires positioning and clinical evaluation of flaps of skin and subcutaneous tissue fed by isolated perforating vessels and potentially suitable for transplantation in another part of the body. Perforators travel from their source vessels to the skin surface, through or between deep musculature. Well vascularized flaps are good candidates for transplantation. [0002] For example, abdominal donor site flaps have become the standard for autologous breast reconstruction since the early 1980s. In the abdomen, free fat options range from total transverse rectus abdominis musculocutaneous (TRAM) flaps to isolated perforator flaps, such as the deep inferior epigastric artery (DIEA) perforator flap. Perforator flaps have allowed the transfer of the patient's own skin and fat to other areas of tissue reconstruction in a reliable manner with minimal donor site morbidity. Flaps that relied on a random pattern of b...
